Description

5-(1,3,2-Dithiarsolan-2-yl)-2-[(1E,3E,5E)-5-[5-(1,3,2-dithiarsolan-2-yl)-1,3-dihydro-3,3-diMethyl-1-(4-sulfobutyl)-2H-indol-2-ylidene]-1,3-pentadien-1-yl]-3,3-diMethyl-1-(4-sulfobutyl)-3H-indoliuM Inner Salt is a sophisticated, functionalized cyanine dye derivative featuring a unique inner salt structure and dual dithiarsolane moieties. This compound is engineered to deliver exceptional photostability and specific reactivity, making it a critical component for advanced material synthesis and high-precision optical applications. It is primarily sought by researchers and manufacturers in the fields of organic electronics, non-linear optics (NLO), and as a specialized precursor for functional dyes and sensors.

Application

• Advanced Organic Electronics: Key building block for synthesizing novel organic semiconductors and charge transport materials.
• Non-Linear Optical (NLO) Materials: Used in the development of materials for optical limiting, frequency doubling, and electro-optic modulation due to its extended conjugated system.
• Functional Dye Synthesis: Serves as a specialized intermediate for creating near-infrared (NIR) absorbing or emitting cyanine dyes with enhanced stability.
• Chemical Sensor Development: Utilized in the design of selective chemosensors, where the dithiarsolane groups act as recognition sites for specific metal ions or analytes.
• Photodynamic Therapy (PDT) Research: Investigated as a potential photosensitizer precursor due to its strong light absorption characteristics.
• Surface Modification & Labeling: The reactive sulfur-arsenic groups can be used for surface attachment or bioconjugation strategies in material science.
